Answer:
d
Step-by-step explanation:
5x -2
Answer choices:
a. 2-5x
b. 3-5 +2x
c. 5x-2x
d. 2x-2+3x
a.
2-5x can be rewritten as -5x+2, which is not the same as 5x-2
b. 3-5 + 2x can be rewritten as -2 + 2x or 2x-2 which is not equivalent to 5x-2
c. 5x-2x is 3x
3x doesn't equal 5x-2
d. 2x+3x-2 = 5x-2
This expression is equivalent to 5x-2
Firstly, let's convert 10x + 2y = -2 to slope-intercept form (y = mx + b):
10x + 2y = -2
2y = -10x - 2
y = -5x - 2/5
The slope is -5. Parallel lines have the same slope; the question provides the y-int (12), so our equation is:
y = -5x + 12
Hope this helps.

hoh(x) = x
Answer:
If Carley ran the 400 meter run in a total of 55.7 seconds and she beat the record by 1.3 seconds, you would add 55.7 and 1.3
55.7+1.3= 57 seconds
The past school record for the girls 400 meter run was 57 seconds
Hope this helps ;)
For domain 2x sqrt(2+x)>0
x>0,2+x>0,x>-2 combining
we get x>2
f'(x)=[1/{2x sqrt(2+x)}][{2x/(2 sqrt(2+x))}+2 sqrt(2+x)]
